SGM2080
SGM2080 is Low Noise and High Accuracy LDO manufactured by SG Micro.
DESCRIPTION
The SGM2080 is a CMOS, fast transient response, low noise and high accuracy linear regulator. It is capable of supplying 500m A output current with typical dropout voltage of only 70m V. The operating input voltage range is from 1.5V to 5.5V. The fixed output voltage range is from 0.55V to 4.2V and adjustable output voltage range is from 0.55V to 5.0V.
Other features include an open-drain power-good (PG) output, logic-controlled shutdown mode, short-circuit current limit and thermal shutdown protection. The SGM2080 has automatic discharge function to quickly discharge VOUT in the disabled status.
The SGM2080 is available in a Green TDFN-2×2-6AL package. It operates over an operating temperature range of -40℃ to +125℃.
